I am usually okay with all other AH's and take them often. My face has swelled up and is all red and itchy. I am not having my typical allergic reaction (itchy eyes, shallow breathing, sneezing, and ear canal itchiness) that I do to allergens I usually treat. My GP thought I had Lupus when I presented this rash symptom 10 years ago. Which I am convinced is due to my taking Reactine before the rash broke out then but I could have just paired the neutral stimuli to the reaction and successfully conditioned myself. My current pharmacist agreed with my decision to use a steroid cream, such as cortisone, to abate the red, itchy, rashy face. If you have searched this and have the same problem, there you go! I would however like to know the cause of this reaction and/or information on the underlining neuropathology concerning histaminergic receptors and drug antagonists/agonists in reference to desloratadine which I can't seem to find anywhere! Any info is greatly appreciated :) I’ve just had an allergic reaction to the antihistamine (AH) brand Aerius, desloratadine. I am usually okay with all other AH’s and take them often.

There are many non-medicinal ingredients in Benedryl and its clones. I had a similar case where it was found that the color additive was the culprite. In the literature, there are cases of preservatives and stabilizers causing immune reactions. Without testing each seporate additive, it is only a guess what may have caused the reaction. In my case, it was found that the patient had an allergy to die. My two cents. Very interesting case. There are many non-medicinal ingredients in Benedryl and its clones.
